1、Designation:D826020Standard Specification forHot-Applied Asphalt Aggregate-Filled Mastic1This standard is issued under the fixed designation D8260;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number in
2、parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This specification covers hot-applied asphalt aggregate-filled mastics for repairing distresses in asphalt pavements andhydraulic concrete pavements.
3、These distresses include,but arenot limited to:depressions,wide cracks not suitable for cracksealing,pot holes,corner breaks and longitudinal jointdistresses,and other repairs smaller than those requiringremove and replace procedures.1.2 The values stated in SI units are to be regarded asstandard.No
4、 other units are included in this standard.1.3 The text of this standard references notes and footnoteswhich provide explanatory material.These notes and footnotes(excluding those in tables and figures)shall not be consideredas requirements of the standard.1.4 This standard does not purport to addre
